    摘要: An image processing apparatus that converts input image data into printable image data is provided. The apparatus performs screen processing on the input image data, and determines whether moiré occurs in screen image data generated by the screen processing unit for a target pixel in the input image data. Depending on the determination result made by the determination unit, the apparatus outputs one of a screen pixel value in the screen image data for the target pixel and a value obtained by converting an input pixel value into a printable pixel value based on intermediate data, as a value of the target pixel in the printable image data, the intermediate data being generated by replacing a screen pixel in the screen image data that is determined to have moiré by the determination unit with the input pixel value in the input image data.

    摘要: A processing apparatus processes input pixel data by referring to pixel data of peripheral pixels. The processing apparatus divides an input image in a first direction, inputs pixel data of a divided image divided in the first direction in a second direction crossing the first direction at a right angle, and stores the inputted pixel data. When a pixel to be referred to for processing the stored pixel data is not included in the divided image, the processing apparatus outputs pixel data of the reference pixel based on the stored pixel data, and processes the stored pixel data by referring to the pixel data of the reference pixel.

    摘要: This invention scans a block using a window having a size of p×q pixels, and encodes p×q sub-block data each formed from pixel data at relatively identical positions in windows. A blocking unit receives a 16×16-pixel block image. A sub-block division unit scans the received block for each 2×2-pixel window, and generates 2×2 sub-block data each having a size of 8×8 pixels. Each sub-block is formed from pixel data at relatively identical positions in windows. A variable length coding unit encodes each sub-block data. When the sum of encoded sub-block data exceeds an allowable encoded data amount, a sub-block elimination unit eliminates encoded sub-block data until the sum becomes equal to or smaller than the allowable encoded data amount. The sub-block elimination unit outputs the remaining encoded sub-block data as encoded data of a block of interest.
